Not necessarily; imagine you witnessing someone getting shot several times only for the bullets to be pushed back out and the holes to close. I don't think anyone would believe you even if you did say something. Afterall, these clones are clandestine operations in themselves. So no one would know if they really existed except higher up officials. So she could go running all she wanted, wouldn't make much of a difference to the general population or low ranked officials because it would seem like she had lost her mind and was spouting nonsense.
Besides that fact,even if she did report a murder he'd be done and gone by the time anyone got back. And its not like he's a serial killer, he wouldn't have a MO. So her own frustration over telling everyone what she saw and them not believing her could propel her to hunt the truth down.
